Error: read ECONNRESET

Hi brianc, this is my first Bug report, so please don’t blame me for bad style:)

I have an issue with loosing connections. This happens after upgrading to node v0.10.1. I used v.8x? before and it worked. I am developing with Windows 8.

Maybe this happens because the Garbage Collector was modified in the new release? I wrote a simple mocha test that shows the problem. var pg = require(‘pg’);

describe('pg', function(){
  this.timeout(65000);
  describe('connection', function() {
    it("should throw no error for 1 min", function(testDone) {

      pg.on("error", function(e){
        //"Error: read ECONNRESET" is thrown for me after 30sec
        testDone(e)
      });

      pg.connect("tcp://postgres:1234@localhost/postgres", function(err, client, done){
        client.query("select 'something'", function(err, result){
          done();
          if (err) return testDone (err);

          setTimeout(function(){
            testDone();
          }, 60000);
        });
      })
    });
  });
})

Debugging this lead me to the assumption, that it is caused by the garbage collector, that is trying to destroy the tcp socket used by the database, but maybe I am completly wrong with this.

I still get this error when trying to connect in Windows 7 x64.

here’s the log:

Hello boys brian forum and apologize for the inconvenience … primaremante tell but a month I’m using the “pg” package ago, I worked well … hize as stated in the documentation building a pool and applying it in the constructor configurations for connection to postgres; but then I got an error -> ECONNRESET on the console when attempting to connect to postgres and a consultation; now I am using Windows 10 x64, postgreSQL 9.5 and node v4.6.0, I would greatly appreciate some clarification’m going with this two weeks without finding answers.

This is the error console. error fetching client from pool identificasion { [Error: read ECONNRESET] code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' }

This is the code and the connection:

_bd.js_***

`var pg=require(‘pg’);

var config = {
  user: 'postgres', //env var: PGUSER
  database: 'TallerII', //env var: PGDATABASE
  password: 'postgres', //env var: PGPASSWORD
  host: 'localhost', // Server hosting the postgres database
  port: 5432, //env var: PGPORT
  max: 100, // número máximo de clientes en la pool
  idleTimeoutMillis: 30000, // how long a client is allowed to remain idle before being closed
};
var pool = new pg.Pool(config);


pool.on('error', function (err, client) {
  console.error('idle client error', err.message, err.stack)
})
    module.exports.basedatos=pool;`

*****************************_index.js_

` var express = require(‘express’); var router = express.Router();//declarando un objeto router para ser mandado a la app var session= require(‘express-session’); var pg=require(‘pg’); var bd=require(‘…/bd.js’); var pool=bd.basedatos;

router.post(‘/Usuario/identificasion’, function(req, res, next) {//aui se le asigna las rutas console.log(req.body.xlogin,‘tb’,req.body.xpassword); pool.connect(function(err, client, done) { if(err) { return console.error(‘error fetching client from pool identificasion’, err); } client.query('SELECT * FROM DATOS WHERE(login=$1 and password=$2 and estado=1) ', [req.body.xlogin,req.body.xpassword],function(err,result){ done(); if(err) { return console.error(‘Error de ejecución de consulta’, err); } var JsonR= new Object(); JsonR.status=“resp”; JsonR.valor=true; // res.json(result.rows) console.log(JsonR); res.json(JsonR)

        });
    });
    pool.on('error', function (err, client) {
        console.error('idle client error', err.message, err.stack)
    })

// res.render(‘ModalLogueo’); });`
